Description

We studied local dynamics of three substituted polyacetylenes in glassy states using a quasielastic neutron scattering technique in an energy range from -2 to 10 meV and found a clear correlation between the local mobility and the gas permeability in these polymers. On the basis of the Q dependence of the relaxation rate we will discuss possible motions related to the gas permeability. (author)
